DEFINING CONDITION OF PRESSURE AROUND THE UNDERGROUND OPENING TRAPEZOIDAL IN SHAPE, SUBSTRUCTURED BY ANCHORS IN MULTILAYERED DEPOSITS INVESTIGATED BY THE METHOD OF FINAL ELEMENTS
The computer program ADINA is used for the pressure analysis on the model of the underground opening, trapezoidal in shape in layers of lignite. An analysis was made before, during and after the setting of three and five anchors. The theory about pressure distribution for secondary and tertiary pressure condition in the roof and board sides of the ...
